Abstract
A liquid blow-molding method for molding a delamination container from a resin container material. The resin container material includes an outer layer, an inner layer, and an ambient air introduction hole. The delamination container includes an outer layer body and an inner layer body, which is laminated on the inner side of the outer layer body in a manner such that the inner layer body is separatable from the outer layer body. The liquid blow-molding method includes the container molding step of molding the container material into the delamination container by supplying a pressurized liquid into the container material; and the inner layer body separation step of separating the inner layer body from the outer layer body by sucking the liquid out of the delamination container.
